Abstract
Background: Aluminium interfer with calcium functions changes the biological processes dependent on this ion. Aluminium enters the body from different sources such as drinking water, kitchen containers and drugs.
Objective: To evaluate the effect of aluminium on rat's sperm count, testis, vas deferens and epididymis weight.
Methods: The experiment was performed on four group of rats (n=13). In addition to control group three test groups consumed 0.625, 1.25 and 2.5 mg aluminium per gram diet for 60 days. Finally, vas deferens, epididymis and testis were removed from the body and weighted. Spermatozoids were counted by hemocytometer. Testis was placed in bouan fixator. After 48 hours, samples were sectioned and stained with automatic stainer.
Findings: The findings indicated that sperm count per gram of tissues in vas deferens, epididymis, testis and the weight of this organ significantly decreased in comparison with control group. The number of leydig cells was also decreased in the groups which consumed the diet containing 1.25 and 2.5 mg aluminium per gram diet.
Conclusion: It can be concluded that high aluminium intake can be effective on reproductive system of the rats. The exact mechanism needs further study.

Abstract
Background: Preeclampsia is one of the common complications of pregnancy in under- developed countries and is caused by many predisposing factors such as gentics, immunologic and environmental factors.
Objective: To determine the relationship between preeclampsia and obesity.
Methods: The study was conducted on 180 preeclamptic women as case group and 180 healthy pregnant women as control group in Shahid Bahonar hospital of Kerman. Variables such as age, height, weight and parity were measured.
Findings: The average age and parity of the case and control group were 24.7×3.4, 1.6×0.7 and 24.74×3.4, 1.55×0.7 respectively. 43.9% of cases were pre-eclamptic and 16.7% had normal obesity. The 0.99 confidence interval between obese rather than normal women (OR: 3.91) was 2.02 - 7.4. There was a significant relationship between obesity and pre-eclampsia (p<0.01).
Conclusion: Women should be trained to control their weight before pregnancy to prevent the probable maternal and fetal mortalities.
368Medical MycologyTreatment and recurrence of vaginal candidiasis after oral and intravaginal treatmentKhorsandiM. Modares GilaniM.KhosraviAR.17200042252922102008
Abstract
Background: Candida vaginit is one of the most common causes of vaginal discharge. Longterm and unsystematic treatment results in incomplete treatment and recurrent disease.
Objective: To evaluate the degree of treatment and recurrence of disease after oral and intravaginal treatment.
Methods: The study was conducted on 65 women having vaginal candidiasis. The subjects were randomly divided into 2 groups in which 32 cases received a single oral dose 150 mg of fluconazole and 33 women 200 mg of intravaginal clotrimazole given daily for 3 consecutive days. Favorable clinical response of both groups was measured by Z-test.
Findings: No significant difference was observed in favorable clinical response of both groups after one-week treatment. The degree of recurrence of disease in fluconazole and clotrimazole group was 6.9% and 9.7% respectively in which Z-test provided no significant difference in manifestation of symptoms one week and one month after the treatment.
Conclusion: The findings indicated the similar effect of oral fluconazole therapy as well as clotrimazole vaginal tablets however, further research is recommended to investigate the recurrence of disease after oral fluconazole therapy.
369OrthopedicsThe effect of Lumbosacral support on spinal muscle fatigue KazemiB.FotohabadiMR.17200042303622102008
Abstract
Background: Wearing back support is of great importance in helping muscles action in heavy works.
Objective: To evaluate the effect of lumbosacral support on the degree of spinal muscle fatigue in normal persons.
Methods: The study was conducted on 52 normal females as "case-control" group using Isostation B-200 unit. Three isometric contractions with maximum effort in flexion and extension were applied for each case in the first session without using back support. Then, fatigue exercise was performed with 50% of maximum muscle power in flexion and extension and the maximum isometric power was again measured. On the next day, the same procedure was performed using back support.
Findings: Increase of the average of torque, power, maximum and average angular speed was significant while wearing back support (P<0.05). Also, the mean of maximum torque and maximum angular speed in last repetitions, with and without back support were significantly decreased in comparison with first repetitions (P<0.05).
Conclusion: Since using lumbosacral back support will cause improvement in speed of repeated motions, less function and delayed fatigue of paravertebral muscles, the use of back support during working hours in heavy works is highly recommended.

Abstract
Background: Intestinal parasites are one of the health complications of under developed countries and are common among children.
Objective: To determine the prevalence rate of intestinal parasites among retarded school-children in Qazvin.
Methods: This study was conducted on all 6 to 12 year old retarded school-children in Qazvin province (Misagh and Freshteh in Qazvin , Andisheh in Alvand and Fajre Mohammadieh in Zibashahr). The faeces specimen of all the cases were abtained in disposable plastic containers and faeces test was performed using direct method and Eter formula.
Findings: The findings indicated that 146 (56.6%) out of 258 cases were infected by intestinal parasites. The infection was mostly due to zyardya (37.2%). The infection was mostly prevalant in 6 to 7 year old retarded school-boys who had uneducated parents. The prevalence rate of parasites was higher in Qazvin.
Conclusion: Preventive measures and finally treatment steps seems to be necessary due to the high prevalence rate of intestinal parasites among retarded school- children.
376ENTRelationship between hemodialysis and sensorineural hearing lossMojabiMA.17200042717622102008
Abstract
Background: Hemodylisis might load to sensori neural hearing loss. Prompt diagnosis and proper treatment.
Objective: To evaluate the relationship between hemodialysis and sensorineural hearing loss.
Methods: A group of 43 patients under the procedure of hemodylisis were compared with a control group of 43 patients who were in the same age range and sex.
Findings: It was concluded that hemodiatic patients had reduced sensori-neural hearing ability, especially in higher-frequencies in both sexes. Reduced hearing sensation was higher infemales. The causative factors in reduction of hearing sensation were as follows: Hypotension,Osmotics , Uraemic neuropathy , Embolism and Electrolyte fluid during the dialysisprocedure. Duration of dialysis and the serum-level of creatinine and PTH didnot play anydecisive role in the loss of hearing sensation.
Conclusion: There is relationship between hemodoalysis and sensorieural hearing loss especially higher frequencies in both sexes.
377PediatricsEtiologies of pneumothoraces in the NICU of Mofid children hospitalHasanzadhM. NouriH.17200042778122102008
Abstract
Background: Pneumothorax is the most common air leak syndrome and far more frequent in the neonatal period than any other time of life.
Objective: To evaluate the etiologies of pneumothoraces in the neonatal intensive care unit (NICU).
Methods: In a prospective study, Barotrauma, Secondary pulmonary infections, unskilled endotracheal intubation, asynchrony between the patients breathing and ventilator and ventilation with self-inflating bag were studied on 50 NICU patients of Mofid children hospital.
Findings: MAP was above the critical level in 18% of the cases. 72% of cases had pneumothoraces in the right side and 16% bilaterally. Asychrony was seen in 38.6% of the cases, secondary pulmonary infections in 46% and malposition of ET tube in 36%. Ventilation with manual bag were done in all cases. The bags lacked manometer and pop-off valve.
Conclusion: Barotrauma had the main probable role in the etiology of pneumothoraces and is probably caused by self-inflating bags without pop-off valve and manometer.
